The beetle is 2.05–3.19 mm long. It has a black body with a ferruginous head and legs. The body is elongate, showing a distinct constriction between the pronotum and elytra in dorsal view, and a faint dorsal constriction in profile. The rostrum features a median carina that terminates at the forehead, flanked by a pair of submedian ridges. The furrows between these ridges contain rows of erect, piliform scales. Just behind the epistome, the ridges are shortened, and the epistome itself bears a transverse, angular ridge with a prominent median denticle.[1]
The pronotum projects subangularly at the anterolateral corners and has an indistinct subapical constriction. Its surface is coarsely rugose-punctate, with each puncture containing a suberect piliform scale, and a median ridge is present. The elytral striae are deeply impressed, each bearing a row of suberect piliform scales. The intervals are raised (costate) and transversely rugose, with the costa of interval 2 shortened at the base. Interval 7 is swollen near the apex and slightly projects laterally. The elytral apex is extended ventrally, forming a beak-like shape. The meso- and metafemora have an anteroventral ridge that forms a faint blunt tooth. The metafemur also bears a subapical stridulatory patch and a transverse row of denticles. Abdominal ventrite 5 has a shallow pit near the apex.[1]
The penis is moderately curved ventrally in profile, with subparallel sides in the basal half that gently diverge anteriorly. The apex has a small rounded median extension. The apodemes are twice the length of the penis body, and the ductus ejaculatorius lacks a bulbus.
Elytral coloration varies from completely black to ferruginous at the base and along the sutural interval. Females have a more slender body, while males are slightly broader, especially across the humeral region. The female rostrum features a pair of lateral furrows and submedian furrows that continue apically as coarse punctures; the epistome is simple. The female abdominal ventrite 5 is flat.[1]
